Mouse/KB battery life read as "0%"

[Luke Faraone]

Despite being fully-functional, my Apple Magic Mouse is shown to be in the "discharging" state at 0%. It is also marked "rechargable", which is false -- you need to replace the batteries when they run out.

Output of `upower --dump` attached.

I have the same problem.

Same problem here with Lenovo BT Laser Mouse with trusty.
The right battery level was displayed with trusty but since kernel update to 3.13.0-26 it only shows 0%.
